Table 4: PMN Functions in untreated patients with solid tumors. The chemotaxis numbers present the average number of migrated PMN per high-power field after counting 20 high-power fields ± standard deviation. The percentage of ingested Candida albicans that were killed after 2 hrs incubation with PMN was calculated by determining the viability of 200 intracellular yeast particles. The mean number of phagocytosed yeast particles per 100 PMN is presented ± standard deviation.
